Finding Production matrix

Question

A=  0.8    0.2     D=   6         X= ?

      0.1    0.4             3              ?     

         

Answer 1

I'm just going to go ahead and assume that AD = X (make sure that's what the problem actually is).

 

Here's a nice looking solution: http://www.wolframalpha.com/input/?i=%7B%7B0.8%2C0.2%7D%2C%7B0.1%2C0.4%7D%7D+*+%7B%7B6%7D%2C%7B3%7D%7D

 

Basically, it's going to be a column vector with 0.8*6 + 0.2*3 = 4.8 + 0.6 = 5.4 on top, and 0.1*6 + 0.4*3 = 0.6 + 1.2 = 1.8 on the bottom.
